Be it'known that I, HARRY .lVnsTNnn, a'

The princlpal feature of the invention? consists in the novelconstruction and arrangement of parts whereby the oil which is fed under pressure is atomized and thoroughly mixed with vapor and is then subjected to the heat of the'burner and brought to a high state of vaporization, the vaporized fuel being projected from a nozzle and mixed with pro-heated air.

In the drawings, Figure 1 is an eleva tiona-l part vertical sectional viewof the dir line 2+2 of Fig. 2. I p Fig, 2 is a top plan view of the device. Fig. 3 is a plan view ofthe-end of the fuel delivering nozzle.

In the'construction ofthe device herein shown av double burner is illustrated, one of the burners beingin section and it will be understood that the description of one applies to both.

A base plate 1 preferably of rectangular form is provided with an upwardly extend-Q 25 is cast'integral with thetop or themember 21an'd connects with the; hole 2% and ing edge flange 2 and a pair of circular flanges 3 arranged one at: each end. Be

tween the circular flanges and central of the width of the base plate is arranged a pair of bosses 4 having central openings there-- through, which openings are threaded at the lower end. To either side of the bosses at are arranged circular openings 5 extending through the base plate.

A circular shaped and tapering member 6 is supported upon legs 7 above each of the circular portions bounded by the flanges 3, said legs fitting within the flanges and the bottom edge 8, which is here shown of serrated form, is placed above the top of the said flange 3. Supported upon each of the members 6 is a circular casing 9 termed with a tapering inner wall 10 which fits Specification of Letters Patent.

over the top of the taperedmember Sand is securedthereto by a set screw 11.

.The top 12 of the casing 9extends horizontally inward and is provided with a central circular opening 13 and a hole 14 is arranged at one side of the central open-' lngand preferably toward the center of the" base. The outer wall 0'5 the casing 9 is hollow and forms a circular water chamber lo to which water is fed through a pipe 16 which entersthe bottom of the casing.

' A block l 7 is formed with a pair oi down wardly pro ecting nipples18which fit into the upper end of the openings to the bosses A and- L-shaped holes 19*e tend upwardly from the bottom of the nipplesand open to the ends'of the block. I

A- tubularcoil 20 is arranged within the.

casing 9,v the bottom end thereof being connected to the adjacent hole 19 in the block Patented ea. 6, 1921.1

17 and theupper end extending through the'hole 14 in'the top of. said casing, the

coil being arranged centrally within the casing.

ofthe openings 5 in the base'and these extend upwardly having right angula-rlyar ranged upper ends extending inwardly over the cas1ngs'9;and'- each having a convergent .80 A tubular member 21is fitted into, veach opening 13 in the topofthe casing to direct a flow of air into the said casing.

A boss 23 is formed on theunder side of the horizontal portion of the tubular menuleadsto a central nozzle opening26 arranged in the under side. A boss 27 extends upwardly; from above the nozzle 26 and in this boss is threaded a needle valve 28 which regulates the flow of vaporized oil through the nozzle. c

A coupling 29 is threaded into the circular opening. 5 and into this coupling is threaded a tubular member 30. The mem ber 30 is provided with a central cylindrical longitudinal orifice 31, which tapers inwardly at the upper end'and leads to a plurality of fine holes 32 formed in the eX- tremity. A nozzle 33 is threaded into the lower end of the member 30 and is provided with a tapered end 34: having a small central opentemperature or vapor from said chamber.

'An oil pipe 36 is connectedto the lower end of the nozzle 33 and is provided with a suitable regulating valve 37 toregulatethe feed of the oil., The oil and'water areintermingled at the point of the nozzle and are projected throughthe small holes in the end of-the tubular member 30 and are thereby mixed to a suitable extent.

The mixture thus ejected from the mem her 30 passes into a chamber 38 in the 'coupling 29 andthe upper end of said coupling is formed with a plurality'of very fine holes 39 through which the vapor and oil mixture is forced, thus reflecting a further mixture of same as it passes into the coil 20 through.

the holes 19 in the block 17.

In the operation of this device the burner is first heated by igniting a suitable fuel such as gasolene placed in the cup formed by the flange 3 which thoroughly heats the coil andvaporizes the oil mixture therein to a sulficient extent toignite' the same at the mouth of the nozzle 26. The flame thus produced induces a flow of air through the tubular" member 21 which mixes thoroughly with the burning gas and produces a very hot flame" which is projected downwardly into the casing 9. The flamestriking the base is then spread outwardly around thebottom of the circular member G and the whole burner is completely enveloped therein, thus heat ing the base plate and the water chamber and the air tubes 21. r a, i

The vaporized water' and oil mixture is converted into a highly volatile gas within the coil 20 and the water supplyiswmaiatained at a high temperature'fand the supply of air passing through the heated tubes is pre-heated to a high temperature before mixing with the gas.

of a very desirable nature, aslow grade oils can be used to very greatadvantage and the admixture of water with the oil creates steam within the coil 20 and the oil vaporizing in thepresence of; the steam creates a thorough mixture producing a highly combustible gas.

I claim as my invention is:

1. An oil burner, comprising, a base, a circular casing open at the bottom and supported above the, base and having an open- .ing in the top, a tube having its open lower end secured in an opening in the base, said tubeextending upwardly beside said casing and having 1ts upper end extending over air nozzle in the'under side arranged over the opening in the top of said caslng, a gas nozzle supported centrally of said air nozzle, a tubular-coil arranged in said casing ing-said casing, an air tube arranged beside said casing and having a nozzle directed downwardly toward the opening in" the top] of said casing, a gasnoz'zle arranged cen-. trally of sald air nozzle, a tubular coil arranged within said casing having one end connected with the gas nozzlefan oil feed connected with sa d coll, a waterpipe connecting said water chamber with said coil,-

and a mixing chamber arranged between said feeds and the coil. I 3. An oil burner comprising, a base, a casing supported above said base, an air tube leading upwardly besidesaid casing and extending'over the top thereof and having a nozzle projecting downwardly, a vaporizing coil arranged within said casing, a gas nozzle arranged in the head of said air tube and adapted to direct a flow of gas downwardly centrally of' the air nozzle;- a' water chamber surrounding said casing,- 'a feed nozzle connected with said coil-having an inner nozzle leading from the oil supply and-an orifice surroundlng said oil nozzle a connected with the water chamber; and a The results obtained from thls deviceare finely perforated member arranged at :the inward end of the feed nozzle: r a
